MACHINE FOR SPINNINGlAND TWISTlNG YARN.

SPECIFICATION forming part of Letters Patent No. 398,270, dated February 19, 1889.

Application filed .Tuly 5, 1887. Serial No. 243,371. (No model.)

T0 all 107mm t may concern:

Be it known that I, GEORGE B. LUKENS, a citizen of the YUnited States, and a resident of Camden, Camden county, New Jersey, have invented certain Improvements in Machines for Spinning and Twisti ng Yarn, of which the following` is a specification.

The object of my invention to provide simple and efficient means for elfecting a double twist of the strands or bers for each rotation of .the spindle.

In the acconil'ianying :lra\\ings, Figure I is a view, partly in elevation and partly in section, showing a spinning device constructed in accordance with my invention; and Figs, 2 and 3, sectional views, on a larger scale, of portions of the device.

In Ilig. il, a and l1 represent upper and lower bearing-rails for the spindles d and d2 of a flier, d, the upper portion of the said spindle being tubular and having a lateral outlet for the passage of the strand or strands, and said upper portion of the spindle having wit-hin the iiier a pendent portion, e, which carries the bobbin f, on which the spun or doubled yarn is to be wound, said bobbin being supported upon a disk, g, which has on the under side springs 7L, engaging with recesses t' in the lower end of the pendent portion of the spindle e, as shown in Fig. l.

As the upper face of the disk g is in frictional contact with the under face of the bobbin, there will be a constant tendency of the latter to turn with the disk and spindle e; but the pull of the yarn upon the bobbin resists this tendency, so that the bobbin rotates and the yarn is' wound thereon only so fast as is permitted by the delivery of yarn to the bobbin.

The lower spindle of the flier is tubular for the reception of a rod, k, which is secured to and moves vertically with the usual lifterrail, m, which can be operated by mechanism similar to that now employed in spinning machinery, and said lower spindle of the flier is grooved externally, so as to form a whirl, d', for the reception of the band n, whereby the Iiier is rotated at high speed.

The upper end of the rod k has a projecting arm, p, at the outer end of which is a socket, s, forming a bearing for the lower end of a spindle, t, the upper end of which is preferably in skeleton forni, and has at the top an axial eye, c, through which the thread is delivered to the bobbin, the spindle having near the bottom a passage, a, extending laterally to the side of the spindle. Projectingl from the spindle is an arm, flu, which engages with one of the bars of the flier d, so that for every revolution of said flier there is a revolution of the spindle '/r, a weighted arm, u", on the opposite side of the spindle serving as a counter-balance to render uniform the effect ol' centrifugal action of the spindle.

The rovings of which the yarn is to be composed, or the independent strands if a doubled thread is to be produced, are fed by suitable rolls to the tubular end of the flier-spindle and pass laterally from the same, thence down to an eye, u", on the projecting arm u, thence to the passage u of the spindle t, and thence up to the axial delivery-eye r at the top of the latter, from which the thread passes to and is wound upon the bobbin. It will thus be seen that the strand takes a course which returns upon itself, and that both in the first part of the course-that is to say, from the feed-rolls to the upper end of the spindle-and in the return course, or from the passage u to the bobbin, the strand receives twist dependent upon the speed of rotation of the iiier, the twisting-spindle t rotating at the same rate of speed as the flier, so that the amount of twist imparted to the strand or strands is double that which it would receive if the twist were imparted by the flier alone.

The filled bobbi'n can be readily doffed from the lower end of the pendent spindle e when the twisting-spindle t and its carrier have been lowered to their full extent, the springfingers h being forced from the recesses t' of the spindle when sufficient downward pressure is exerted upon the bobbin, and in applying an empty bobbin the latter and the disk beneath the same are simply raised on the pendent portion c of the nier-spindle until the spring-fingers engage with the notches in said spindle, as shown in Fig. l.

It will be evident that in place of the bearing-bars a and h being fixed and the bar m movable the reverse construction may be adopted, t-he bar m being fixed and. the nec- TOO essary traverse movement being imparted to the bars ce and b, so as to properly lay the thread upon the loobbin, the Construction shown being preferred, however, as the flierwhirl always remains in the Same plane in re- Speet to the driving-drum, and thus provides for a more effective and uniform action of the driving-belt than when the reverse construetion is adopted.

I elaiIn as my inventionl. The Combination of the flier, the bobbinearrier thereon, a tubular spindle loeated at one side of the axis of the flier and having an axial delivery-eye at its upper end, an arm projecting from said spindle and engaging with the flier, a hearing for the spindle, and a rod carrying said bearing and passing through one of the spindles of the Hier, all substantially as specified.
